GAUGE vANI) WORK HQLDEB `Application led July 9, 1928. Serial No. 291,449.

This invention is in` a gauge and' a work holder therefor.

More particularly, the invention relates to when the rollers have been finished and are rea-dy for assembly in the'completed bearings that these finished rollers be gauged for circumferential size. This circumferential sizing must be Within certain prescribed manufacturing tolerances, so that, when the fin-l ished roller is assembled in a bearing, itwill freely roll to make a perfect anti-friction bearing. Suchprecision in the size of rollers is especially important in the case of tapered rollers for use in tapered roller bearings, and the present disclosure illustrates the invention as applicable to the gauging of tapered rollers.

Accordingly, the objects of this invention are to provide an improved gauge and work holder for testing the circumferential size of rollers which have been inished and are ready for assemblyin roller bearings; to provide an improved work holder which is simple and edective ,in speedingJ up the testing operation; to provide a simple form of sizing block which can be produced at a minimum of cost; to provide such a block which will hold the work in an improved manner by preventing endwise and sidewisdisplacement of the work; and, lastly, as applicable to tapered rollers, to provide a novel form of work holding block provided with means for supporting the roller in such a. manner that its upper edge, which will be in contact with the operating member of a gauge, always lies in substantially a horizontal plane. Other objects will be apparent to those skilled in this art. Y

*These desirable objects are accomplished incombination with.V a .gaugefstructurd of a block whichv receives thework in a manner to be specified, so that the work is in engagement with a member which operates the gauge for indicating the circumferential size of the work being tested.

In Athe accompanying sheet of drawings there has been illustrated the preferred embodiment of the invention, and ,in these drawings,- l

Figure 1 is a side elevational view of the gauge structure in combination with the sizing block vand a tapered roller therein, which is in position to have its size gauged;

Figure 2 is 'a front elevational view of the same structure shown in Figure 1;

Figure 3 is an end view of the sizing block partly in section,with a tapered roller there,- in, as seen along the line 8-3 of Figure 5;

Figure 4 is a front sectional view of the same structure, as seen along the line 4-4 of Figure 5; and

. Figure `5 is a top plan view of the sizing block.

The gauge structure shown comprises aare provided for xing the position of the l.' y

block 14 on the rack 13. The lower end of the gauge is provided. with a stem 18 designed to be operated by a lever 19 which in turn is operated by a plunger 20 adapted to contact the work.

The bed of the machine 10 carries an anvil V or block 21, which is provided with a rectangular opening o'r depression on its top side, indicated at 22, said opening including an extension 23 from one corner thereof,'as best shown in Fi ure. Snugly tted into one of the ends o the depression or opening 22 is a vertically arranged end wall member ers, slopes in twodirections. One df these slopes-is in the direction of the end wall 24, and the other slope is in the direction of the side wall 25, as best shown in Figures 3 and 4:.M It can now be seen thatthe floor part, thel end wall part, and the side wall part [cooperate to form a pocket adapted to receive, in the preferred form illustrated, a tapered roller bearing. The slopes mentioned are complementairy or coincide with the conical slope of the tapered roller and, as a result,l the upper edge of the roller always lies ina horizontal plane. The gauge structure, it will be understood, has been adjusted in such a manner as to cause the lower end of the plunger 20 to contact the upper edge of the rollers adjacent its large end. y

In operation, after the block has been assembled, an operator takes the finished taered roller and lays it in the pocket of the lock with the enlarged end of the roller contacting the lower end-of the plunger 20. As the work lies loosely in the pocket, the operator can rotate the same by hand and, as a result, any variations in circumferential size will re-act on the plunger 20 and cause the needle of the gauge 15 to give an indication of any inaccuracies in size, as will be understood.

From this descri tion it can now be appreciated that a simp e gauge and sizing block structure has been provided which achieves ali of the-desirable objects heretofore recited. It is to be understood that it is intended to cover all such changes and variations of the preferred embodiment herein illustrated as do'not materially depart Ifrom the spirit and scope of this invention as is indicated in the appendedl claims.

What is claimed as new is:

1. The combination with a measuring structure comprising a frame, an indicator gauge thereon, and a plunger for operating the same, of a sizing block on the frame, said block being rovided with an opening, a vertical side wa l member therein, a vertical end wall member therein, a floor member therein, said members cooperating to form a pocket for rotatably supporting a rollerin engageentwith vthe plunger which operates the 1ndicator. .l

2. The combination, with a measuring device comprising a frame, an indicator` gauge thereon, and..v a plunger for operatin the same, of a. block on the frame, said bloc ing provided with a rectangular opening, a. vertical` side wall member therein, a vertical ber in the opening said parts cooperating to forni a pocket for loosely supporting a tapered roller in a manner to cause its upper edge to lie in substantially a horizontal plane.

4. A block for use in a gauge structure, said block having an opening provided with a re- `tially in a horizontal plane.
